Values are means ± SD from the quantification using HPLC-UV of 10 individual capsules and are reported based on the number of capsules ingested by participants for each formulation: STE: 4 capsules; TEP: 3 capsules; NOV: 2 capsules; PHYT: 2 capsules; TPG: 1 capsule. See Supplemental Methods for details. BDMC, bisdemethoxycurcumin; DMC, demethoxycurcumin; HPLC-UV, high-pressure liquid chromatography with ultra-violet spectroscopy; NOV, liquid micellar formulation; PHYT, phytosome formulation; STE, standard turmeric extract; TEP, piperine-curcuminoids combination; TPG, Turmipure Gold formulation.
